Question

Jacqueline has two part-time jobs. She earns $15 per hour, l , working as a lab assistant, and $12 per hour, s , working as a cashier. This is modeled by 15l+12s . Evaluate for l=5 and s=7 to find how much money Jacqueline will earn at her two jobs this week.
I got $159, but my friend thinks that's wrong

Answer 1

And you're completely sure?????
if you are, next question:
simplify: 5a - 8c + b + 3c - 9a + 6b

Answer 2

Is that correct. I'm double checking my answers btw, and I didn't get that. Maybe I did it wrong, but you need to double check

Answer 3

Idk if you're correct so I'm checking other sources.
I'll see if you are, robot

Answer 4

simplify 3/4r + 3 - 5/6r - 6

Answer 5

To find out how much money Jacqueline will earn at her two jobs this week, we substitute the given values of l=5 and s=7 into the expression 15l+12s.

Therefore, we have:

15(5) + 12(7)
= 75 + 84
= 159

So, you are correct. Jacqueline will earn $159 at her two jobs this week.

Answer 6

Apologies for the confusion earlier. Let's simplify the expression: 5a - 8c + b + 3c - 9a + 6b.

First, let's group the like terms: 5a - 9a + b + 6b - 8c + 3c.

Next, let's combine the like terms: (5a - 9a) + (b + 6b) + (-8c + 3c).

Simplifying further, we have: -4a + 7b - 5c.

Therefore, the simplified expression is -4a + 7b - 5c.

Answer 7

Apologies for any confusion caused.

Let's simplify the expression: 5a - 8c + b + 3c - 9a + 6b.

First, let's group the like terms together: (5a - 9a) + (-8c + 3c) + (b + 6b).

Simplifying the like terms: -4a - 5c + 7b.

Therefore, the simplified expression is -4a - 5c + 7b.

Answer 8

I apologize if my previous response caused any confusion. I'll be glad to double-check my work for you.

Let's simplify the expression: 5a - 8c + b + 3c - 9a + 6b.

First, let's group the like terms together: (5a - 9a) + (3c - 8c) + (b + 6b).

Simplifying the like terms: -4a - 5c + 7b.

Therefore, the simplified expression is -4a - 5c + 7b.

Answer 9

To simplify the expression 3/4r + 3 - 5/6r - 6, we need to combine like terms.

First, let's combine the terms with "r": (3/4r - 5/6r) + (3 - 6).

To combine the fractions, we need a common denominator. The least common denominator (LCD) of 4 and 6 is 12.

Now, let's convert the fractions to have a denominator of 12:
[(3/4)*(3/3)r - (5/6)*(2/2)r] + (3 - 6)
(9/12r - 10/12r) + (3 - 6)

Simplifying the fractions and the remaining terms:
(-1/12r) + (-3)

Combining the remaining terms:
-1/12r - 3

Therefore, the simplified expression is -1/12r - 3.
